WebSep 8, 2024 · This study studied the removal of benz[a]anthracene (BA) and dibenz[a,h]anthracene (DBA) from soil. BA and DBA are high molecular weight hydrocarbons that have been included in the list of persistent organic pollutants by the US Environmental Protection Agency (ATSDR 2005).They might be toxic and are probably human … WebCC16 concentration decreased monotonically with increased high molecular weight OH-PAHs (∑HMW OH-PAHs) when ∑HMW OH-PAH concentration was over 0.67μg/mmol Cr. CC16 mediated 22.13% of the association between ∑HMW OH-PAH and FVC among individuals with higher ∑HMW OH-PAH.

WebMay 18, 2024 · The results showed heavy PAH contamination at both site S1 (0.38–3342.5 mg kg⁻¹) and site S2 (0.2–138.18 mg kg⁻¹), of which high molecular weight (HMW) PAHs (4-, 5-, and 6-ring compounds ... WebHigh-molecular weight PAHs are more toxic than lighter relatives, and also have a higher tendency to bind onto air particles (i.e., particle matter, PM). PM is a major constituent of air pollution. Adequate assessment of the biological impact of PM requires the analysis, not only of the effects on human health, but also on the environment. sifl rates 2021 second half irs
